Question

我试图在Tomcat 8.0.3上部署我的spring应用程序。 servlet容器使用jdk 1.0.7_51。我能够通过

进行部署

mvn tomcat7：plugin

但是当Tomcat尝试运行应用程序时。在日志文件中，我得到了这个例外：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in URL [file:/home/myApp/apache-tomcat-8.0.3/webapps/myApp/WEB-INF/classes/database.xml]: Invocation of init method failed; nested exception is java.lang.SecurityException: class "org.eclipse.persistence.sessions.coordination.CommandProcessor"'s signer information does not match signer information of other classes in the same package

我也跑

mvn依赖：tree | findstr eclipse

我得到了这个结果

我该如何解决？

Answer 1

您有多个JAR提供包org.eclipse.persistence.sessions.coordination中的类，但其中一些JAR是签名的，一些是未签名的。 Java类加载器不允许这样做。

修复的难易程度取决于具体情况。

如果签名JAR提供的类也由未签名的JAR提供，并且应用程序CAN在没有签名的JAR的情况下运行，则只需删除已签名的JAR。

如果未签名的JAR提供的类也由签名的JAR提供，并且应用程序CAN在没有未签名的JAR的情况下运行，则只需删除未签名的JAR。

如果签名JAR提供的类也由未签名的JAR提供，但是应用程序无法在没有签名的JAR的情况下运行，那么您将需要强制Tomcat加载未签名的JAR （s）首先。以下是ASF如何通过Jira在Tomcat 8上运行Jira 6.2解决此问题。这需要添加到Web应用程序的context.xml中。

<Resources>
  <!-- Trick to force this JAR to be searched for classes before all others
       to work around a Jira bug -->
  <PreResources className="org.apache.catalina.webresources.FileResourceSet"
                base="${catalina.base}/webapps/jira/WEB-INF/lib/jira-api-6.2.jar"
                webAppMount="/WEB-INF/lib/jira-api-6.2.jar" />
</Resources>

与删除一样，您可以将其翻转以使签名的JAR首先加载。

如果上述方法都不起作用，您可以解包已签名的JAR并在没有签名的情况下重新打包它们，但如果在任何地方都需要签名的JAR，则可能会破坏某些内容。

我解决了改变我的pom：

 <dependencies>

    <dependency>
        <groupId>org.eclipse.persistence</groupId>
        <artifactId>org.eclipse.persistence.jpa</artifactId>
        <version>2.5.1</version>
    </dependency>

    <dependency>
        <groupId>org.eclipse.persistence</groupId>
        <artifactId>eclipselink</artifactId>
        <version>2.3.2</version>
    </dependency>

</dependencies>

为：

 <dependencies>

    <dependency>
        <groupId>org.eclipse.persistence</groupId>
        <artifactId>org.eclipse.persistence.jpa</artifactId>
        <version>2.5.1</version>
    </dependency>


    <dependency>
        <groupId>org.eclipse.persistence</groupId>
        <artifactId>eclipselink</artifactId>
        <version>2.5.1</version>
    </dependency>

</dependencies>

我只修改了eclipseLink的版本
